In short - how much light is received by a surface. 75 lumens to candela = 75 candela. The candela per square metre (cd/m2) is the SI unit of luminance and NIT is the older non-SI unit mostly used in the US. La unidad estándar de la luminancia es la candela por metro cuadrado (cd/m2). When compared with lumens, candelas are a metric for the intensity of the light generated by a lamp. Using the metric system, a lumen is measured by a square meter or a lux. This page features online conversion from lux (lumen per square meter) to nit.These units belong to different measurement systems. According to the National Institute of Standards and Technology, The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian (a candle). Luminance measure the luminous intensity projected on a given area or in a given direction whereas brightness is a subjective attribute of light perception. This one is very simple: it defines how much luminous flux is spread over a given area. The formula used in meter-candles to foot-candles conversion is 1 Meter-Candle = 0.0929030400000796 Foot-Candle.
